<div><h2 id="Description">Description</h2>
<div class="description"><p>Angular's wrapper for <code>window.setTimeout</code>. The <code>fn</code> function is wrapped into a try/catch
block and delegates any exceptions to
<a href="api/ng.$exceptionHandler"><code>$exceptionHandler</code></a> service.</p>

<p>The return value of registering a timeout function is a promise which will be resolved when
the timeout is reached and the timeout function is executed.</p>

<p>To cancel a the timeout request, call <code>$timeout.cancel(promise)</code>.</p>

<p>In tests you can use <a href="api/ngMock.$timeout"><code>$timeout.flush()</code></a> to
synchronously flush the queue of deferred functions.</p></div>
